TRACK-CURVE FOR STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 437,566, dated September 30, 1890.

' Application filed January 30, 1890. Serial No. 338,546. (No model.)

To all whom it may concern.-

Be it known that I, FRANK. S. CHURCH, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigamhave invented a certain new and useful Improvement in Curves for Cash and Parcel Carrier Appa ratus; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to to which it pertains to make and use the same, reference being had to the accompanying 1drawings, which form a part of this specifica- In the drawings, Figure 1 is a plan View illustrating my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail View, and Fig.4 likewise a detail view, of the parts of the oontrivance. Fig. 5 illustrates a varia-. tion.

It is the purpose of my invention to produce acurve which shall be adjustable to a larger or smaller radius and adapted for use with any ordinary or novel arrangement of cashcarrier and parcel-carrier apparatus.

2 5 In carrying out my invention, A represents a sector pivoted at its center a. Upon its periphery'is a series of pins a.

B is a strap of spring metal-as, for instance, spring-steelsaid strap extending at its ends go beyond the limits of the sector A. This is provided with orifices corresponding with the pins upon the periphery of the sector, as shown at b, and B represents pins upon the strap itself adjacent to its ends. Adjacent to these 5 pins, and between the same and the ends of the strap, there are milled channels 2), within which the line-wire is adjusted. These milled channels start from a point adjacent to the pin B, and, passing thence toward the other 40 end of the strap, the said channels become deeper and deeper until at the upper edge it is so that it brings the wires centrally above the edge of the band at 12 Then from this point outward to the end of the strap the upper edge of the strap is channeled to admit the wire and brings the upper surface of the wire upon the general level of the top of the band.

O is a strap of phosphor-bronze or other suitable material, which binds the line-wire upon the steel band at its extremities.

The operation of the device is as follows: The line-wire is brought over the end of the strap or band into the groove there cut for it and down through the channels 1) beneath the pin B. It is then caused to pass over the next pin and under the following one, over the next, and so on to the other end of the strap, where it is carried out in the same way that it was admitted. Straps O are then placed in position and hold the wire in place. This contrivance may be somewhat varied. Thus, for instance, the strap B might have a channel on its under side at B as shown in Fig. 5, in which event a projecting tenon B from the sector would fit within this groove to hold the strap upon the sector, and there should in that event be one protectingpin at the center of the sector extending through a hole in the middle of the strap to prevent any longitudinal displacement of the strap along the sector or disarrangement of the sector with relation to the strap. In this latterconstruction the wire is trained the same as before, except that it would pass over this central pin at the middle of the band and beneath the pins B at the two extremities of the band, as before explained.

It is obvious that in a device which is constructed according to my invent-ion the curve is made adjustable, so as to fit any angle which might be required in practice, the tension of the band itself holding it always into contact with the sector. If it is deemed best, however, there might be a screw or bolt joining the band atits middle point with the periphery of the sector.

What I claim is- 1. An adjustable curve for cash or parcel carrier apparatus, the same consisting of a go sector A, in combinationwith a separate spring metallic band 13, substantially as and for the purpose described. I

2. The combination, with the sector and. the separate spring-band, of the pins a, adapted to pass through the band for the purpose of holding it in place, substantially as described.

3. The combination, with the sector, of the spring-band provided with pins B' and having channels b b substantially as described.

4. The combination, with the sector, of the spring-band havin g pins B and provided with 5 grooves b 19 and the straps 0, adjacent to the extremities of the band, substantially as described.
